Weak Lensing from Space III: Cosmological Parameters
Alexandre Refregier, Richard Massey, Jason Rhodes +6
Weak gravitational lensing provides a unique method to directly map the dark matter in the universe and measure cosmological parameters. Current weak lensing surveys are limited by…
Weak Lensing from Space II: Dark Matter Mapping
Richard Massey, Jason Rhodes, Alexandre Refregier +8
We study the accuracy with which weak lensing measurements could be made from a future space-based survey, predicting the subsequent precisions of 3-dimensional dark matter maps, p…
Weak Lensing from Space I: Instrumentation and Survey Strategy
Jason Rhodes, Alexandre Refregier, Richard Massey +1
A wide field space-based imaging telescope is necessary to fully exploit the technique of observing dark matter via weak gravitational lensing. This first paper in a three part ser…
Image Simulation with Shapelets
Richard Massey, Alexandre Refregier, Christopher J. Conselice +1
We present a method to simulate deep sky images, including realistic galaxy morphologies and telescope characteristics. To achieve a wide diversity of simulated galaxy morphologies…
